vips_draw_flood (
VipsImage* image,
double* ink,
int n,
int x,
int y,

)
Description [src]
Optional arguments:
test: test this imageequal: fill while equal to edgeleft: output left edge of bounding box of modified areatop: output top edge of bounding box of modified areawidth: output width of bounding box of modified areaheight: output height of bounding box of modified area
Flood-fill image with ink, starting at position x, y. The filled area is
bounded by pixels that are equal to the ink colour, in other words, it
searches for pixels enclosed by an edge of ink.
If equal is set, it instead searches for pixels which are equal to the
start point and fills them with ink.
Normally it will test and set pixels in image. If test is set, it will
test pixels in test and set pixels in image. This lets you search an
image (test) for continuous areas of pixels without modifying it.
left, top, width, height output the bounding box of the modified pixels.
ink is an array of double containing values to draw.
